RF340T — 13.56 MHz transponder for SIMATIC RF300
The Siemens 6GT2800-4BB00 is an RF340T read/write transponder in the SIMATIC RF300 family, operating at 13.56 MHz with a 106 kbit/s transfer rate. It carries 8189 bytes of user memory on FRAM/EEPROM with an additional 4-byte UID and 20 bytes of one-time-programmable (OTP) memory. Block-by-block write protection on the OTP region prevents accidental overwrite of critical identification data after commissioning. Rated IP67/IPx9K, the housing withstands high-pressure washdown and temporary submersion — typical for food-and-beverage or pharmaceutical lines where the tag follows a product carrier through cleaning cycles. The PA12 material and silicon-free construction suit cleanroom-adjacent zones where outgassing or silicone contamination is a concern. Temperature range splits by operating state: -25 to +85 °C during read/write access, -40 to +85 °C outside the read/write area and during storage. That means the tag can survive a hot wash cycle (storage limit) but must be within the narrower band when the reader actually pulls data — a detail that matters if the tag sits on a pallet passing through a hot tunnel.
Fastened with two M3 screws through the 48 × 25 × 15 mm anthracite housing. No DIN-rail clip; the form factor is a flat tag meant for direct attachment to a workpiece carrier, pallet, or product holder. The 105 mm read range is reader-dependent — Siemens application note 67384964 covers the pairing matrix. Protocol is RF300-specific, not ISO 15693 or generic HF — it talks only to SIMATIC RF300 readers (RF310R, RF320R, RF350R). No cross-vendor compatibility; the tag expects the Siemens handshake.
Minimum order quantity is 5 units per the description.
